It makes sense that I will lose volume but I'm willing to lose some volume for portability.
I mostly got into e-calling because I want to hunt cougar; longer sets, unique cat vocalizations. From what I've read I'll need to cut a fresh track to have the best success and where I hunt that means a lot of walking; private timber, locked gates. This caller may not have been the best choice for my needs (portability) but it was a good price and had cougar vocals on it.
It uses a 30W TOA now so I would assume the electronics (driver) could handle the 10W TOA. I know nothing about the electronics aspect of these callers so I just wanted to make sure either the 610 or 610T would work, but maybe it's not that simple.
I've tried to contact WT regarding this question about converting to the 10W TOA but have been unsuccessful using both phone & email.
